If a student completes several recordings in a session, which one will be scored?

We first try to choose the earliest "full-length" recording, which we define as a recording that is at least 55 seconds long that a student has recorded on a given day. If there are no full-length recordings, we then choose the longest recording. This way, if a student accidentally creates a short recording after she has recorded successfully, the short recording will be ignored and only the successful recording will be scored.
